[CF-Devel] issues with random maps

[Preston Crow]

I've been playing the random maps a lot recently.  (High-level undead maps
are great for experience.)  In doing so, I've run into a number of issues
that need to be examined and probably fixed.

Exits on Exits:

I sometimes see exits stacked on top of each other.  I think I may have
once seen the up and down stairs on each other, but I've often seen a hole
to a special treasure map on top of the stairs.

Monsters on Entrance:

Monsters should never be placed on the entrance to the map.  When this
happens, you have to fight your way out, as you get placed a square or two
away from the way back.  Similarly, generators should not be placed on the
entrance.

Traps Bypassed:

When there is a chest that requires a key to open, it often will have a
large number of traps.  However, you can ignore them.  I find that if I
pick up the chest, activate it, and drop the contents, I'm free to pick
them up, drop the chest, and walk away without ever setting of a single
trap.  (Of course, I like to disarm them anyway so as to get the
experience.)

Traps on Walls:

I've seen some maps generated that had traps on most of the walls.  I was
able to search and disarm them, though running into the walls would not set
them off.  Either they shouldn't be there, or they should be set off by
bumping into the wall (which would require some new code, I suspect).

Disconnected Maps:

I discovered this by casting "show invisible" to locate spectres.  I was on
a map that had two separate areas.  The walls separating them were three
squares thick at the narrowest point.  (I went into dm mode to see what was
up.)  There was no way to get over to the other area.  Fortunately, the
stairs down were in the same area as the stairs up, so it didn't really
mess anything up that time.

Impossible to Reach Area Due to Keys:

I found one map where one walled-off area was accessible only by using
strange keys to open the walls around a chest.  Unfortunately, the keys in
question were all in that walled-off area, so I couldn't reach them.  I
suppose there's a chance that one was in an icecube, but I don't think so.
